Overview
The American College of Sports and Medicine (1) estimates that the average adult takes between 5,000 and 10,000 steps per day. The brunt of this activity is borne by the bones, muscles and ligaments of the foot. Healthy feet have strong, wonderfully flexible ligaments which are designed to support standing, walking and running. Plantar Fasciitis (pronounced “plantar fash-ee-eye-tis”) is defined as inflammation of, or damage to, one of the most important ligaments in the foot – the plantar fascia. The plantar fascia ligament is located along the sole of your foot. It is made up of fibrous tissue that stretches outward from the heel bone, like a strong piece of elastic, and then branches out across the arch and through the ball area of the foot toward the toes.
Causes
When the foot moves, the plantar fascia stretches and contracts. Plantar fasciitis is caused by the repetitive overstretching of the plantar fascia. If the tension on the plantar fascia is too great, this overstretching causes small tears in the plantar fascia. This in turn causes the plantar fascia to become inflamed and painful. Factors that contribute to the development of plantar fasciitis include having very high arches or flat feet, gender, while anyone can develop plantar fasciitis, it tends to occur more commonly in women, exercises such as running, walking and dancing, particularly if the calf muscles are tight. Activities or occupations that involve walking or standing for long periods of time, particularly on hard surfaces, wearing high heeled shoes or shoes that do not offer adequate arch support and cushioning, being overweight, additional weight increases the tension on the plantar fascia, poor biomechanics, extra tension is placed on the plantar fascia if weight is not spread evenly when standing, walking or running. Some cases of plantar fasciitis may be linked to underlying diseases that cause arthritis, such as ankylosing spondylitis.
Symptoms
Among the symptoms for Plantar Fasciitis is pain usually felt on the underside of the heel, often most intense with the first steps after getting out of bed in the morning. It is commonly associated with long periods of weight bearing or sudden changes in weight bearing or activity. Plantar Fasciitis also called “policeman’s heel” is presented by a sharp stabbing pain at the bottom or front of the heel bone. In most cases, heel pain is more severe following periods of inactivity when getting up and then subsides, turning into a dull ache.
Diagnosis
Your doctor will perform a physical exam to check for tenderness in your foot and the exact location of the pain to make sure that it’s not caused by a different foot problem. The doctor may ask you to flex your foot while he or she pushes on the plantar fascia to see if the pain gets worse as you flex and better as you point your toe. Mild redness or swelling will also be noted. Your doctor will evaluate the strength of your muscles and the health of your nerves by checking your reflexes, your muscle tone, your sense of touch and sight, your coordination, and your balance. X-rays or a magnetic resonance imaging (MRI) scan may be ordered to check that nothing else is causing your heel pain, such as a bone fracture.
Non Surgical Treatment
If you walk or run a lot, cut back a little. You probably won’t need to stop walking or running altogether. If you have either flatfeet or a high arch, ask your doctor about using inserts for your shoes called orthotics. Orthotics are arch supports. You will need to be fitted for them. If you are overweight, losing weight can help lessen your heel pain. If your job involves standing on a hard floor or standing in one spot for long periods, place some type of padding on the floor where you stand.
Surgical Treatment
Surgery should be reserved for patients who have made every effort to fully participate in conservative treatments, but continue to have pain from plantar fasciitis. Patients should fit the following criteria. Symptoms for at least 9 months of treatment. Participation in daily treatments (exercises, stretches, etc.). If you fit these criteria, then surgery may be an option in the treatment of your plantar fasciitis. Unfortunately, surgery for treatment of plantar fasciitis is not as predictable as a surgeon might like. For example, surgeons can reliably predict that patients with severe knee arthritis will do well after knee replacement surgery about 95% of the time. Those are very good results. Unfortunately, the same is not true of patients with plantar fasciitis.
